Abstract: Abstract Titanium diboride graphite composite articles are produced by mixing TiO2, petroleum coke and a binder to form a plastic dispersion. Articles are shaped by molding or extrusion and baked to carbonize the binder to form a baked carbon-TiO2 composite.  the article is impreqnated with a molten or dispersed boron compound, then heated to drive TiB2 forming reaction.  The article is then further heated to a graphitizing temperature to form a graphite-TiB2 composite useful as a cathode component in a Hall aluminum reduction cell.

Abstract: IMPROVED METHOD OF PREPARING CULTURED DAIRY PRODUCTS     Abstract of the Disclosure A method for the production of cultured dairy products, such as buttermilk, yogurt or sour cream, by the controlled fermentation of a liquid medium consist-ing of a major portion of light cream, milk, lowfat milk or skim milk or reconstituted skim milk powder or butter-milk powder, or a mixture of these two components.  The liquid medium is fermented using a bacterial fermentation culture.  The fermentation of the medium is allowed to proceed for sufficient time to achieve a pH in the range of between 6.2 to about 4.9, at which point the liquid medium is then cooled to a fermentation rate-reducing temperature and acidulated to a pH of 4.7 or below using food grade acids such as those selected from the group consisting of lactic, citric or acetic acid.

Abstract: AIR CONTROL MECHANISM HAVING    NOISE SUPPRESSION MEANS          ABSTRACT OF THE DISCLOSURE          The invention provides an airflow control mechanism for use in an air duct for controlling airflow through the duct.  The air flow control mechanism includes a frame positionable in the duct, and a plurality of blades supported by the frame and extending transverse-ly to the direction of the air flow through the air duct. At least one of the blades is supported for pivotal movement about its longitudinal axis and has an elongated edge moveable toward and away from an elong-ated edge of another of the blades to restrict air flow through the duct.  A fiber material strip is applied to at least one of those edges, the fiber material strip including a substrate bonded to that edge and a plural-ity of closely spaced fibers projecting transversely from the substrate, the fiber covering being functional to prevent the generation of a high frequency standing wave between the adjacent surfaces of the blade.

Abstract: ABSTRACT OF THE DISCLOSURE           A well packer which is anchored downhole within the bore of a casing string by opposing slips.  The well packer is hydraulically set.  One embodiment of the inven-tion allows the packer to be released from its downhole lo-cation  by cutting the packer mandrels below the packing elements.  The invention is particularly adapted for use with a dual string well packer.  However, the anchoring and releasing mechanism of the present invention can be readily adapted for use with a single string well packer.  Use of the present invention with a dual string packer is parti-cularly desirable because it allows combining the features of hydraulic setting downhole, opposing slips for better resistance to differential pressure in either direction, and selective releasing of the packer from the downhole location.
